Water tank cleaning is essential to keep your water safe to drink. Crystal Clear Tanks is your answer to keeping your full or empty tank pristine clean with minimal loss of water. Our water tank cleaning method works for most tank types, including concrete, poly (plastic), fibreglass and galvanised iron tanks.
We remove the sludge and foreign matter from the bottom of the tank to leave clean, hygienic water. The remaining water can be sanitised at the customers request.
Harmful bacteria levels increase when a build up of debris decompose on the bottom of a tank. This leads to a thick layer of sediment that needs to be removed. The sediment can result in blocked water filters, washing machine filters, ceramic tap wear & tear, etc. This debris and sludge often consists of leaves, plant blossoms, bird droppings, dust, dye, ash, from the roof. Occasionally animals including rats, snakes, frogs and possums enter through the downpipes, manhole or overflow pipes and die in the water. The dead animals can result in smelly, bad tasting water with high levels of bacteria.
In addition to providing water tank cleaning, Crystal Clear Tanks can advise the following measures for clean drinking water;
- Overflow flaps/screens to minimise mosquito breading and vermin entering the tank.
- Leaf beater devices to filter leaves and other debris entering through the down pipes from the roof.
- First flush diverters to prevent the first runoff of water from entering the tank. This first runoff often contains debris and contaminants from the roof.
- Manhole covers to prevent sunlight entering the tank to avoid algae growth.
Additionally, you should always ensure gutters are kept clear and free of debris. This may include installing gutter guards and pruning trees near the roof.
“Tanks should be examined for accumulation of sludge at least every 2-3 years” – NSW Health
NSW Health and the enHealth Council of Australia recommend tanks are examined for accumulation of sediments every 2-3 years or if sediment is evident in the water flow. They recommend water tank cleaning and installation of first flush devices to ensure your water is clean, free from bad odours and not discoloured.
